What's What: The 7 (!) Liquids of Machshirim. More on impurity.... Continuing the discussion of whether the liquids in the slaughter house in the Beit HaMikdash can become impure - including wine and oil, not just the blood and water. Also, trying to line up the sages and their opinions - Levi, Rav, and more. Plus: R. Pappa on the question of tumah d'Orayta, and his position that the purity here is Halakhah le-Moshe mi-Sinai. Which has its own rules. Also, the location of the liquid is a game-changer, whether in vessels or on the ground, in terms of when impurity kicks in (or doesn't). Plus - what happens to all that impure liquid, when it leaves the Beit HaMikdash?! And what if they left while pure? The liquids' origins - where it achieves its status of pure or impure - makes the difference.
